Students should be able to describe the role of waves in transferring energy, explain the relationship between frequency/wavelength; and construct/use models/simulations to represent waves, including how amplitude of wave is related to its energy.
Model a longitudinal (compression) wave and diagram/label/describe the components (wavelength/compression/frequency); model a transverse wave and diagram/label/describe the components (wavelength/amplitude/frequency/crest/trough)
Compare longitudinal/transverse waves and their characteristics; plan/conduct investigations related to the refraction/reflection/diffraction of longitudinal/transverse waves.
Develop/use a model to describe mechanical waves being reflected/absorbed/transmitted through various materials
Plan/conduct an investigation related to sound (investigation/experimental design or systematic observation/description/measurement, and/or data collection and analysis)
Interpret graphs/charts to determine factors that determine the speed of sound through various materials; identify the property of a sound wave that corresponds to its loudness
Apply scientific principles to compose an argument as to which of several wires of different lengths would produce the highest-pitch sound
